Three. And they were separate 360's. Some, multiple of times. I went through two X-box 360's. Then the third broke eventually, too. My step-dad manually repaired it himself, but, it failed. Again. Just like the other two. xD We've never had the money to get it professionally repaired.
We've wasted money on so many X-box 360's. Its not MY money, but, its my parents money. So its partially my money. >_<

Now I have a kinect. Its been lasting a long time. This is the longest time I've gad a 360. xDBut my brother is ALWAYS playing it. I hope it doesn't give in.

I have never had the red ring of death, I have had something else similar to it though. Instead of the red ring, the 360 burnt out something it used for displays, so all of a sudden one day the display was all sorts of messed up to the point that it just stopped working all together. I sent that one in to go get repaired and 2 years later gave it to my ex's brother. I ended up getting the 360 slim right as it came out, but now its CD Drive has gone bad. About 3 months ago it started to give me issues starting games and now it doesn't read them at all, just says Open Tray.
